Andrews called on UN Member States, including those in the Association of Southeast Asian Nations (ASEAN), the European Union (EU), the United States (US) and China, to hold an emergency summit of all stakeholders, including the duly elected illegally deposed parliamentarians who make up the Committee Representing Pyidaungsu Hluttaw (CRPH).
"Conditions in Myanmar are deteriorating," he said in a press release on Thursday.
"But they will likely get much worse without an immediate robust, international response in support of those under siege," he stated.
According to him, it is imperative that the international community heed the recent call of UN Secretary-General Antonio Guterres for a firm, unified international response.
However, the limited sanctions imposed by Member States do not cut the junta’s access to revenue that help sustain its illegal activities, and the slow pace of diplomacy is out of step with the scale of the crisis.
"The incremental approach to sanctions has left the most lucrative business assets of the junta unscathed," he stated.
"It needs to be replaced by robust action that includes a diplomatic offensive designed to meet the moment," he added.
Andrews stressed that he is receiving reports indicating that the situation in Myanmar is in danger of spiralling further out of control and warned of a dramatic increase in loss of life.
"Without a focused, diplomatic solution, including the hosting of an emergency summit that brings together Myanmar’s neighbours and those countries with great influence in the region, I fear the situation of human rights in Myanmar will further deteriorate as the junta increases the rate of murders, enforced disappearances and torture," he said.
"I fear that the international community has only a short time remaining to act," he concluded.
